Pain reliever

A man went to the dental surgeon to have a tooth pulled. The dentist pulled out a freezing needle to numb the area.

"No way! No needles! I hate needles," the patient shouted.

The dentist started to hook up the laughing gas and the man again objected.

"I can't do the gas thing!” the man protested. “The thought of having a gas mask on is suffocating to me!"

The dentist then asked if the man had any objection to taking a pill.

"No," the patient said. "I am fine with pills."

The dentist said, "Here is a Viagra tablet."

The patient replied: "Wow! I didn't know Viagra works as a pain pill!"

"It doesn't," said the dentist, "but it will give you something to hold onto when I pull out your tooth."

Piltdown man

In 1912, the discovery of the skull known as Piltdown man, the first important fossil human skull ever to be unearthed in England was announced at a meeting of the Geological Society of Great Britain. Charles Dawson, steward of Barkham Manor, an attorney and secretary to the Sussex Archaeological Society; and Arthur Smith Woodward, keeper of geology at the British Museum announced their remarkable find had been made at Piltdown Common. The specimen, known as Piltdown man, occupied an honored place in the catalogues of fossil hominids for the next 40 years. But in 1953, thanks to some rigorous scholarly detective work, Piltdown man was revealed to be nothing more than a forgery, manufactured from modern human and animal remains.
